GEARING.

Patented Oct. 8, 1912.

Application filed July 3, 1912. Serial No. 707,437.

To all whom it may concern:

Be it known that I, ROBERT S. Bnown, a citizen of the United States,residing at New Britain, in the county of Hartford and State ofConnecticut, have invented certain new and useful Improvements inGearing, of which the following is a specification.

This invention relates to gearing, one of the primary purposes of theinvention being to provide effective means whereby a part such as ashaft, can be operated either by power or hand, the construction beingsuch that the two operating means cannot be simultaneously in action. Inthe drawings accompanying and forming part of the present specificationI have shown in detail-one of the several convenient forms of embodimentof the invention which to enable those skilled in the art to practicethe same will be set forth fully in the following description. I do notrestrict myself, however, to such disclosure; I may depart therefrom inseveral respects within the scope of the invention defined by the claimsfollowing said description.

Referring to said drawings: Figure 1 is a side elevation of a metalworking machine involving my invention, and, Fig. 2 is a horizontalsection on the line 2-2 of Fig. 1 looking in the direction of the arrow.

Like characters refer to like parts in both views.

My improvements can be incorporated with utility in various kinds ofmetal working machines, and in fact machines of other types, theinvention not being limited in this respect. In Figs. 1 and 2 of thedrawings I have shown certain of the members of a multiple-spindleautomatic turret-machine such as shown in Letters Patent No. 874,035, ofDecember 17, 1905 granted to George G. Prentice to which reference maybe had. A machine such as thatshownin said Letters Patent includes inits organizawhich need not, therefore, be described, as the same inthemselves constitute no part of the present invention. I have shown asrising from the bed 5 the bearings 7 and 8 usually integral therewithand tied together by the brace 9. This portion of the showing, however,constitutes the subject matter of a separate copending application filedJuly 5, 1912, Serial No. 707 ,658. The bear ings 7 and 8 support thespindles 10. It is needless for me to further describe this part of themachine, the same being set forth in detail in said other application.

The bed 5 is shown provided upon one side thereof with a power operableshaft 11 which may receive its motion in any desirable manner, forinstance by a train of gears operated from some suitable source ofpower, the terminal one thereof being shown and being designated by 12.In axial coincidence with the shaft 11 is a second shaft 13 alsosupported by a bearing on the bed 5, the shaft 13 having a reduced endfitting a socket in the shaft 11. Through clutch means I can connect ordisconnect the shaft 11 and the shaft 13, and it will be apparent thatwhen these two shafts are connected the shaft 13 will be rotatedprovided the shaft 11 is being turned, and when they are dis connectedthe shaft 13 will be thrown out of action. The clutch means shown forputting the two shafts into and out of operative relation will behereinafter described. The cam shaft (3 receives its motion from theshaft 13 through suitable means, for instance such as those now to bedescribed. Said shaft 13 at its inner end has fastened thereto a bevelgear 1 1 in mesh with a substantially similar bevel gear 15 and thetransverse shaft 16 supported by suitable bearings upon the head end ofthe bed 5. Said shaft 16 between its ends is equipped with a worm 17 inmesh with the worm gear 18 fastened to the cam shaft 6. It will,therefore, be clear that when the shaft 16 is turned the cam shaft 6will be operated a similar extent. The said shaft 16 as alreadydescribed is adapted to be operated by power. It may also as willhereinafter appear be operated by hand, and hand operating means aresuch as to adjust the said shaft 6, so that parts which receive theirmotion therefrom can be correspond ingly adjusted.

The bevel gear 15 is shown located at one r pa i n lu c v member ll. beretracte o as will hereinafter be set forth to be manually operated andwhich through clutch V mechanism as will hereinafter appear is.

adapted to. turn the shaft 21 and therefore through the connectionsalready described, adjust the cam shaft 6. The bed 5 is equipped with asuitable bearing for sustaining the shaft 22 and said shaft fits asocket in the coiiperating shaft 2,1, Owing to the described connectionbetween the two sets of shafts they are effectively supported at theirends presenting in effect, except so far as their motion is concerned,continuous Shafts.

Splined to the, shaft 11 for rotative movement therewith andlongitudinal movement thereon, is a clutch member 23 co'ciperative withthe clutch member 2a fastened to the shaft 13. It will be clear thatwhen the clutch member 23 engages the clutch mem-.

her 241, thetvvo shafts 11 and 13 will be operatively connectedtogether, so that if the shaft 11 be turned, the cam Shaft 6 through theintermediate parts already described will be otated by PQWQ Sp l d o t eaf 21 fo r at on h r the clutch, member 26 fastened t0 the shaft 22. Itwill be evident that when, the clutch members 25 and 26 are connectedtogether and that when the shaft 22 is turned by hand, the cam shaft 6through, the intervening connections already set forth, can berofatedtions of which have already been described are so related thatthe shiftable members thereof cannot be simultaneously advanced. Thatisto say when the clutch member 23 is ad anced he c tch member 25 willbererac ed nd ice versa, so at h alv of the clutches cannot be engaged atthe,

same time,

which are provided with pins or studs entering peripheral grooves orchannels in said respective clutch halves after the well-known. mannerin clutch shifting devices. The two forks 28 and29 andthe shaft, are sorelated that when said shaft is rocked in. one

direction one clutch member such as the member 23 will be advanced toengage thecompanion clutch member 24, whilethe com The two. clutches.the halves or secthereby disengage it from the cotiperating clutchmember 26. To facilitate the operation of the clutch member shiftingdevices one of the forks as that denoted by 29 may be provided with anupwardly extending portion 30 terminating in a handle 31 which can begrasped by the attendant to simulta 'neously operate the clutch members23 and v 25. It will be assumed that the clutch member 23 is disengagedfrom the clutch 1ne1nher 2 1 and that the clutch members 25 and 26 arein engagement so. that the vcam shaft 6 can be operated by hand but notby power, notwithstanding the fact that the shaft 11 may be rotating. Tofacilitate the operation L of the shaft 22 the hand crank 32 may beprovided, said hand crank being adapted through suitable interposedgearing to transfer its effect to the shaft 22 for rotating the samewhen occasion therefor isrequired.

.The. said hand crank v32 is fastened to the shaft 33. rotativelysupported by the arm 3% ion the bearing for the shaft 22. Fastened tosaid shaft 33 is a spiral gear .35 in mesh With a Similar spiral gear36on theshaft 22. Therefore, when the clutch members 25 and V 26- areengaged the shaft 6 can be manually adjusted by turning the hand crank32, the i effect of the latter being applied to the shaft .22 throughthe interposed described gears F and the motion of said shaft 22 beingtransferred to the cam shaft through the agency ,of theconnectionsalready described.

with and for longitudinal movement there- Q .1 s the clutc memb r 25 coperative with What I claim is:

2. Ina machine of the class, described, the

combination of a power operable shaft, a second, shaft coaxialtherewith, a. clutch for clutching and unclutching said poweroperableand said coaxial shaft and comprising a movable member, amanually operable shaft,

. a fourthshaftcoaxialwith said manully operable shaft, a clutch forclutching and unclutching said, manually operable shaft and the movablemembers of the respective clutches and adapted when turned in onedirection to advance one of said movable members and to simultaneouslyretract the other movable member and adapted when turned in the oppositedirection to reverse said operation.

3. In a machine of the class described, the combination of a bed, a camshaft extending longitudinally of said bed, a second shaft extendingtransversely of the bed and operatively connected with the cam shaft forrotating the same, a third shaft and a fourth shaft both operativelyconnected with said transversely extending shaft, a power operable shaftcoaxial With the third shaft, a
